I know, I would much prefer a small party (hence the fact we choose an DW!), but my FFIL is one of 11 siblings, my dad is one of 7 and my mom is one of 6, his mom just has 2 sisters, but they all have a few kids (our ages) as well. We both have pretty large groups of friends that we managed to stay in touch with, so it's hard to cut it down. Also, since my FFIL is from Italy, and has family is Australia and New Zealand, it appears that extended family likes to attend functions as well, when they can.
